We went to the lake, something bit me or my child at night, I noticed it only in the daytime, in the morning there was a temperature, I don't know if it appeared because of the bite or just caught a virus, the temperature was for two days and now a couple of hours without a temperature, but the bite is looking like this, right now it's not possible to go to the hospital, I smeared Levocetirizine, made a cold compress, waiting from the pharmacy Fenistil, please tell me who has encountered it, the bite became like that after I scratched it, before it was not so big, I thought it was just a mosquito bite, the child cries when I smear cream.
